2011 Cadillac STS Review

By

Once hailed as the savior of the Cadillac brand, the STS luxury sedan now seems to be overshadowed by the brilliant CTS Sedan, Coupe and Wagon, not to mention the impressive V-Series cars. Still, for those looking for luxury without hair-raising performance, the STS remains a crowd pleaser. Along with its slightly larger cousin, the DTS, the STS' mission is to continue satisfying the aging Cadillac faithful while still appealing to younger, first time buyers. Although it is available with all-wheel drive and a performance package suspension upgrade, the loss of the Northstar V8 engine this year will probably also cost the STS some potential buyers.

You'll Like This Car If...

If you like the crisp lines and modern styling of the CTS Sedan, but need just a bit more rear-seat passenger room, check out the STS.

You May Not Like This Car If...

If you're looking for V8-inspired power or bold styling that stands out in a crowd, the STS probably won't impress you.

What's Significant About This Car?

For 2011, the STS is no longer available with the Northstar V8 engine, leaving the 3.6-liter V6 as the sole power plant. All 2011 STS models are now covered by Cadillac's Premium Care Maintenance program.

Driving the STS

Driving Impressions With only its key fob in our pocket, the 2011 Cadillac STS sensed our presence and unlocked its doors for us. Once inside, a push of a button was all...

that was required to make the V6 engine roar to life. We found the STS' 3.6-liter V6 a strong yet quiet performer, free of vibration and roar even with the accelerator pushed to the floor. On the highway, we averaged close to 28 mpg, which is not bad for a 300-plus horsepower sedan. Our rear-wheel-drive STS was equipped with the performance package which includes Brembo brakes and 18-inch wheels. The standard STS suspension provided predictable handling with minimal body roll and, though the steering response was somewhat soft and slow to react, we still found it easy to maneuver the car in tight turns. Cadillac's StabiliTrak stability control proved admirable in keeping the STS from skidding off course.

Bose 5.1 Studio Surround Sound
The Bose 5.1 Studio Surround Sound option features 15 speakers placed strategically throughout the cabin, including on the tops of the seats and beneath the center console. It delivers great sound.

Supportive Seats
The STS seats show Cadillac has found a nice combination of comfort and support, and they do a good job of holding you in place without being too firm.

2011 Cadillac STS Details
Interior

The 2011 Cadillac STS has a pleasant interior that exhibits a high degree of fit and finish, but its overall design is a bit dated and hardly inspiring. Sparse applications of wood trim dot the STS' interior, which can be had in ebony, cashmere or light gray leather covering the seats, steering wheel and shift knob. Optional equipment, such as the four-color head-up display and Bose 5.1 Studio Surround Sound audio, help liven things up a bit. On Platinum models, suede-like Alcantara fabric replaces the standard cloth headliner, while hand-cut leather coverings adorn the door panels, dash and center console. Rear-seat legroom is better than in the CTS, but it's still not what owners of previous full-sized Cadillacs would call spacious. The large trunk, on the other hand, has ample space for luggage or golf bags.

Exterior

Although from a distance it looks somewhat like a slightly larger CTS Sedan, the STS nevertheless has a character all its own. The STS is some two inches wider than the CTS, and its rear doors are longer with more glass area. The signature Cadillac fender vent and vertical rear tail lights are evident, as is the wide egg-crate grille and stacked HID headlamps. Stylish multi-spoke alloy wheels give the STS a bit of a sporting attitude, as do the trunk-mounted spoiler and shark-fin roof antenna. The STS's tail lights and rear center-mounted stop light employ LEDs, which use less energy and last longer than conventional bulbs.

Notable Equipment
Standard Equipment

The 2011 Cadillac STS has a six-speed automatic transmission, four-wheel anti-lock disc brakes (ABS), traction control, StabiliTrak electronic stability control, dual-zone automatic air conditioning, OnStar, keyless start, auto-dimming mirror, Ultrasonic Rear Parking Assist, Bose audio, navigation, front side-impact and front and rear head-curtain airbags, leather seats, cruise control, leather-wrapped power tilt/telescoping steering wheel and 17-inch painted aluminum wheels.

Optional Equipment

Options are generally arranged by trim level and packages and include onboard navigation, Head-Up Display (HUD), garage door opener, six-disc DVD changer, Bose 5.1 Studio Surround Sound system, HID headlamps, Magnetic Ride Control suspension, limited-slip rear axle, load-leveling suspension, heated rear seats, heated and cooling front seats, 18-inch wheels and tires, Lane Departure Warning, Side Blind Zone Alert and a performance handling package. The Platinum Edition adds Alcantara headliner, unique 18-inch wheels, leather trim interior and Platinum badges. Stand-alone options include all-wheel-drive and a power moonroof.

Under the Hood

The 3.6-liter V6 engine is strong enough to satisfy most owners, and its advanced electronic features, such as the variable valve timing, help maximize fuel efficiency and power.

3.6-liter V6
302 horsepower @ 6300 rpm
272 lb.-ft. of torque @ 5200 rpm

"I inherited this Cadillac from my aunt who passed away at age 100+ she bought this car in 2005 and died at 100 in 2013. Needless to say she put very few miles on it and used it for grocery shopping and doctor appointments..This car is perfect..like show room perfect. I put new tires on it since I didn't want to drive on 2005 tires. I also put in a new battery since that older one wasn't holding a charge since it wasn't driven. I now have a trickle charger holding the battery perfectly. I have a Jeep and don't need two cars. When I got the car the mileage was 17,000. In two years I've put on 7,200 miles on this car."

Just can't beat a cadi . . Literally.

2005 STS

"I have never owned a cadillac, but I purchase this car used, and I have been blown away on how quickly it won me over. The first thing I noticed is that no one passes me on the on-ramp. This 3.6 liter is always purring. It has all leather, heated seats, and a lot of options. This one has the 19" dubs. I wouldn't have ordered them, but my friends are fans. My cousin even called me a baller. This car gets me and my kids where we need to go, and people take notice of me in this car. I just love cruising in it. :)"

"The car runs perfect and is very safe. I Just replaced front breaks and a coil and she purrs with speed, comfort and style with less than 55,000 miles. There is a little tear in the leather on passenger side seat but I have new leather to replace."

"Bought new at $55K, but now only worth $10K, while my '08 Chevy bought new for $51K and now has more miles is still at $20K. Both cars have been excellent performers in both city and highway. My wife and I prefer the Caddy in town, but the Chevy is more comfortable on long 2-5K mile highway trips. YMMV"

"I have owned many cars and this has to be one of the best, if not the best. Have driven it for 103000+ miles and outside of suggested regular maintenance I have not done anything to this car - OEM tires lasted almost 80000 miles and brakes almost 60000. I don't really want to let this car go."
